Utilisation de Retrofit comment analyser JSONArray sans analyse d'objets?

Question

Je suis analyse syntaxique format suivant de JSON:

{ 
msg: "success", 
status_code: 200, 
data: [ 
{ 
.... 
} ] 
} 

et je suis l'analyse à l'aide Retorfit2 dans l'objet suivant:

public class Model { 
    @SerializedName("status_code") 
    int statusCode; 
    @SerializedName("msg") 
    private String statusMsg; 
    @SerializedName("data") 
    private JSONArray data; 

} 

Je veux analyser « données » à JSONArray au lieu de types de modèles spécifiques, indépendamment de sa structure d'objets internes. Mais il donne suite à l'exception, quel est le problème?

Jetez un oeil sur la ligne de code ci-dessous.

`

public class Model { 
    @SerializedName("status_code") 
    int statusCode; 
    @SerializedName("msg") 
    private String statusMsg; 
    @SerializedName("data") 
    private **ArrayList<JSONObject>** data; 

}
